Bruins prepare for Lightning strikes without Patrice Bergeron

Patrice Bergeron was again absent from Bruins practice on Thursday as he continues to recover from a mild concussion suffered in the Game 4 series-clinching win last Friday against the Flyers.

“All I can say is he keeps progressing on a daily basis,” Bruins coach Claude Julien said after Bruins practice Thursday. “He hasn’t been on the ice or done any of that stuff yet so we’re keeping our fingers crossed that thing will be clear and more optimistic as we move forward.”

Bergeron, who has yet to take part in any physical on-ice or off-ice activity, sustained a concussion when Philadelphia’s Claude Giroux finished a check in the Bruins defensive zone early in third period. Bergeron had a difficult time get up from the ice and making his way to the bench. It was the third concussion he’s had in his career in Boston, the second since his most severe concussion when he was checked into the board’s by then-Flyers defenseman Randy Jones in Oct. 2007.
